Welcome!
I have been developing Mac programs and Java programs for approximately 10 years. You can find some my programs on this site. I have ported (and helped port) the following programs to the Mac:
Emilia Pinball
Eternal Lands
Koules.
I’ve also written a full game myself called Trapped. And a mini game called Dual Maze.
These can be found on the Software page.
I’ve written a large number of mini games as part of mini-contests in the #idevgames irc chat room. These can all be found here.
Other miscellaneous programming stuff can be found here
